I have a website using a subdomain. A-record for subdomain and www.subdomain are entered in Cloudflare, and both pointed to the site IP address. Now, I can access the website with subdomain.domain. But, if I access it with www.subdomain.domain, I always get the error message ERR_SSL_VERSION_OR_CIPHER_MISMATCH. Lastly I also uploaded the Cloudflare SSL/TLS Origin Certificates on the website server. It still doesn´t help.
Does anyone have an idea how to resolve this issue?
Thanks in advance.
